Once you repent of your sin and trust in Christ, then God declares you to be righteous—godly, pure, even though you are still a miserable sinner. He forgives you of all your sin! That’s God’s work for us—justification, accomplished at the cross and received only by trusting in Jesus. And the Spirit of Christ, having entered your life, now begins to train you to be actually godly. To become what you actually are. That’s God’s progressive work in us—sanctification, wrought by the Spirit.
